Sdk: Setting EnableDefaultCompileItems to False doesn't remove the files from solution Explorer

Create a ClassLibrary (.Net Core)
Take a copy of Class1.cs and drop in the same folder
you will see of them included
Now edit the csproj and put the below information

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <EnableDefaultCompileItems>False</EnableDefaultCompileItems>
    <TargetFramework>netcoreapp1.0</TargetFramework>
  </PropertyGroup>
 <ItemGroup>
    <Compile Include="Class1.cs" />
 </ItemGroup>
</Project>

Build again , it includes only Class1.cs but the solution explorer shows all files, expected ?

Build

This is because <None> picks them up. @dsplaisted

Another side effect of this reported through VSFeedback is that when the user goes to add a cs file to the project in this state, the None glob picks it up and so it's not passed to the compiler as a source file.

Ah, that's bad.

[srivatsn]

Moving this to SDK since this is caused by the None globs - @dsplaisted are they really useful? I find the None globs more annoying than useful since it picks up all files in that folder

@srivatsn , @livarcocc Any timeline for the fix or known workarounds?

[livarcocc]

@dsplaisted for a work around.

See https://github.com/dotnet/project-system/issues/3181#issuecomment-368396256

maybe None shouldn't include source files?

Yes, I think this is the right fix.

@livarcocc @dsplaisted, we should probably re-triage this. It gets reported a lot and I think @davkean has a good, simple proposal to address it.
